Abstract
Description
- This application claims priority to the U.S. provisional patent application Ser. No. 62/983,566, filed on Feb. 28, 2020, which is incorporated herein by reference in its entirety.
- The present invention relates to an assembly and method for removing a stuck axle hub, and more particularly, the present invention relates to a hub puller for removing a stuck hub without damaging the hub or spindle.
- Removing a stuck axle hub can be a laborious, time-consuming, and difficult task. A mechanic typically hammers the hub repeatedly to loosen the bonds. Additionally, anti-rust compositions are also used to loosen the corrosion. However, such steps often fail, and the repeated hammering may damage the hub and adjacent components of the axle. The last resort is generally cutting down the hub using a cutting torch. The replacement cost of the whole hub can be high. Moreover, the cutting down of the hub may also damage the spindle increasing both the cost and time of service.
- Thus, a need is there for a hub puller that can pull a stuck hub without damaging the hub or axle.
- The following presents a simplified summary of one or more embodiments of the present invention in order to provide a basic understanding of such embodiments. This summary is not an extensive overview of all contemplated embodiments and is intended to neither identify key or critical elements of all embodiments nor delineate the scope of any or all embodiments. Its sole purpose is to present some concepts of one or more embodiments in a simplified form as a prelude to the more detailed description that is presented later.
- The principal object of the present invention is therefore directed to a hub removal assembly that can remove the hub without damaging the hub or axle.
- It is another object of the present invention that the hub removal assembly is economical to manufacture.
- It is still another object of the present invention that the hub removal assembly is easy to use.
- It is yet another object of the present invention that the hub removal assembly is compact and portable.
- In one aspect, disclosed is a hub removal assembly that includes a rectangular bar having a central sinkhole. An elongated lead screw having a proximal end and a distal end. The proximal end of the lead screw is transversely screwed into the central sinkhole. The distal end of the elongated lead screw can be configured as a head that can be turned by a pneumatic tool.
- In one aspect, the length of the rectangular bar is proportional to the diameter of the hub, and the width of the rectangular bar is proportional to a distance between adjacent bolts of the hub. The rectangular bar can fit between the opposite two pairs of adjacent bolts, such as the proximal end of the elongated lead screw can rest against a hub axle center.
- In one aspect, disclosed is a method of removing a stuck hub using the disclosed assembly. At first, the rectangular bar can be mounted between opposite pairs of adjacent bolts while the proximal end of the lead screw rest against the hub axle center. Thereafter, the lug nuts of the opposite pairs of adjacent bolts can be fastened, wherein the nuts can have a flange that rests against the rectangular bar. Once the assembly is mounted tightly on the hub, the lead screw can be turned clockwise, resulting in linear motion of the rectangular bar away from the axle, wherein the hub coupled to the rectangular bar can also be pulled away from the axle.
- These and other objects and advantages of the embodiments herein and the summary will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings
- The accompanying figures, which are incorporated herein, form part of the specification and illustrate embodiments of the present invention. Together with the description, the figures further explain the principles of the present invention and to enable a person skilled in the relevant arts to make and use the invention.

The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention will be best defined by the allowed claims of any resulting patent.
- Referring to
FIG. 1 which shows an exemplary embodiment of the disclosedhub removal assembly 100 for disengaging a hub stuck to an axle. Thehub removal assembly 100 can include arectangular bar 110 and alead screw 120. Therectangular bar 110 can be solid or hollow and made of a rigid and strong material, such as iron. The length of the rectangular bar can be proportional to the diameter of the hub to be removed.FIG. 2 shows thehub removal assembly 100 mounted to ahub 200. The length of the rectangular bar is substantially equal to the diameter of thehub 200. The width of therectangular bar 110 can be proportional to the distance between twoadjacent bolts 210. The width of therectangular bar 110 allows therectangular bar 110 to fit between the twoadjacent bolts 210.FIG. 2 shows the rectangular bar fit between the opposite two pairs ofadjacent bolts 210. Therectangular bar 110 can have a central sinkhole into which the elongated lead screw can be transversely screwed. The central sinkhole can have threads for threadedly engaging the lead screw. Alternatively, a plate having a threaded aperture can be welded to the bottom surface of the rectangular bar, wherein the central sinkhole can be concentric with the aperture of the plate. the bottom surface of the rectangular bar can be in contact with the hub.FIG. 1 shows theplate 130 welded to the bottom surface of the rectangular bar, wherein the threaded aperture ofplate 130 is concentric with the central sinkhole. - The
lead screw 120 can be of an elongated configuration having aproximal end 140 and adistal end 150. Theproximal end 140 of thelead screw 120 can rest against thehub axle center 230. Theproximal end 140 of thelead screw 120 can be flat, as shown inFIG. 1 . The body of thelead screw 120 between the proximal end and the distal end can be threaded, wherein the threads correspond to the threads in the central sinkhole of therectangular bar 110. The threads can be such as the turning motion of thelead screw 120 can be translated to the linear motion of therectangular bar 110. The threaded structure of a lead screw is known in the art for use in linear actuators and jacks. Thedistal end 150 of thelead screw 120 can have a head, wherein the head can be dimensioned such as it can be engaged to a fastening tool. The fastening tool can be a spanner or a pneumatic tool. - The
rectangular bar 110 can also have spacednotches 160 that can be aligned with protrusions of the hub.FIG. 2 shows thehub having protrusions 240 along its inner periphery. Therectangular bar 110 when mounted onto the hub between the bolts can be aligned relative to the protrusions. Theprotrusions 240 of thehub 200 can be inserted into thenotches 160 of therectangular bar 110. - Also, disclosed is a method for pulling a hub stuck to an axle. The
rectangular bar 110 can be mounted onto the hub, such as therectangular bar 110 fits between the opposite two pairs ofadjacent bolts 210, as shown inFIG. 2 . The tip of thelead screw 120 can rest against thehub axle center 230 when thehub removal assembly 100 is mounted to thehub 200.Lug nuts 250 of the opposite two pairs of adjacent bolts can then be fastened. The bolts can have sufficient length for fastening the nuts. The nuts can have a flange that can rest against the rectangular bar. The fourlug nuts 250 shown inFIG. 3 can be tightened against therectangular bar 110. The head of the lead screw can then be engaged to an air tool and turned clockwise against the hub axle center. The turning motion of the lead screw against the hub axle center transforms to the linear motion of the rectangular bar. The rectangular bar moves away from the axle, wherein the hub coupled to the rectangular bar also moves away from the axle resulting in releasing of the stuck hub. - While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
